MAP18: Mineshaft (Jenesis)

MAP18: Mineshaft is the eighteenth map of Jenesis. It was designed by James Paddock (Jimmy), who also composed the level's music track "Airport Chant." The par time is 3:20.

Essentials
Press the button to lower the wall and enter a cave which contains imps and shotgun guys, as well as two big lifts. Go to the east lift and press the arrow button inside it to go down to the bottom level, then follow the passage to a crossroads with a super shotgun and take the south-east path to find a door. Open this door to find imps and one or two revenants (plus shotgun guys on Hurt Me Plenty (HMP) skill level or higher) guarding two more doors, open the south door to enter a hall with another revenant as well as imps that are hiding behind the flaming windows on either side, then go up the steps to a water stream (Hell knights are present here on Ultra-Violence (UV) and Nightmare (NM)) and follow it west until you drop into a dark tunnel. Follow the tunnel north and take the first right, then go east and north to a skull switch and press it; this will lower some bars in the neighboring tunnel to the west, allowing you to reach the red skull key.

Taking the red key will open a monster closet to your left containing zombies as well as a gargoyle switch; pressing the switch raises some rock steps allowing you to climb back up the waterfall to a waiting arch-vile, as well as raising a bridge in the hall leading back to the crossroads. Go back to the big lift and press the up button at the doorway to raise it, then go back up to the starting area and use the west lift to go up to the top level. Kill some imps waiting at the top then walk north to find two revenants guarding a pair of doors - open the north door and kill some imps and a demon waiting in the next room, then go through the west doorway to drop into a water pool with yet more imps and a switch. Flip the switch to raise the water and reveal a baron of Hell behind the window overhead, then step through the window and walk south to find the blue skull key along with one or two chaingunners.

From the blue key, head north-east to a door and go through it to return to the room with the revenants, then go through the north door again before walking north-east to a set of red bars that you can lower using the nearby switch. Follow the hallway north to a mancubus guarding a hole then drop down that hole to land on a ledge with a skull switch requiring the blue key; after pressing it, quickly run north to leap over to a rising bridge (if you miss you can press the skull switch on the bridge to lower it again) then head east past some mancubi and imps into the neighboring room where more imps are guarding another skull switch; press it and dodge the mancubi that are revealed on either side, then go back to the bridge you just raised, where a set of bars have opened leading to a room with two chaingunners and two revenants who are hiding behind the flaming windows, then flip the switch in the north-west corner - this will allow you to collect the yellow skull key elsewhere in the map. Activate the silver lift in the opposite corner and ride it up to the top of the hole you dropped down earlier, where some lost souls have been released, then walk south to see a floor arrow pointing at an opening in the wall. Go through this opening and kill a waiting mancubus, then step on the teleporter it was guarding to go to the yellow key and land on a rocket launcher.

Taking the yellow key will release cacodemons, demons and knights into the room; kill them then go west and north through two doors to find yourself back at the crossroads. Take the north-east path this time and open the door to confront a knight and imps (plus shotgun guys on UV and NM), then go round the corner and turn right to enter a fountain room with a yellow key door. Open this door and dispose of two more knights, then go through and turn left to see a water pool containing demons, as well as an arch-vile on HMP or higher. Enter the water and go straight forward into the dark tunnel to finish the level.

Other points of interest
There are some blue skull bars at the top of the western big lift, which can be opened with the corresponding key. The chamber contains a berserk pack, a rocket launcher, rockets and stimpacks along with an arch-vile.

Secrets

 * 1) Take the east (descending) lift at the start, and at the crossroads, keep going north-east to the next hall. Head towards the yellow key door and turn west to the box of bullets. Lower the wall between the torches, then flip the switch behind it. Head back north and quickly enter the alcove to the east for a plasma gun. (sector 567)
 * 2) Collect the red key, then return to the switch that lowered the bars to the key. A new passage here leads to a door to the windowed room where you can get a plasma gun. (sector 373)
 * 3) After getting the blue key, open the blue bars by the western big lift. Enter this room, then return to the starting room to find a megasphere in the south-west corner. (sector 40)
 * 4) In the northeastern-most room past the red key door, look at the columns on the north side. The north-west column has a hidden gargoyle switch on its north side. Press it to raise a step to the mancubus platform at the south-east end, the step onto that platform (if it has not lowered, you did not use the other switch in the room, so do so now). Press on the recessed wall to find a water passage taking you to an energy cell pack. (sector 355)
